This would appear to be the result of the current digitisation project at the National Library of Scotland, which also ties in with the EDINA/NLS Addressing History project. At present there are three Internet Archive hosted Edinburgh directories fully searchable on the project's beta site at http://addressinghistory.edina.ac.uk, where the results can also be plotted on contemporary maps. The team have recently stated that if the beta is judged successful, the project will be extended to cover over 400 trade directories from across the country.
